Heart disease risk factors in Los Angeles County safety personnel

Area of Science:

• Cardiology
• Preventive Medicine
• Public Health

Background:

• Heart disease remains a leading cause of mortality worldwide.
• Identifying individuals at high risk for coronary disease is crucial for preventive interventions.
• Existing risk assessment tools, like the Framingham index, are valuable but may benefit from complementary approaches.

Purpose of the Study:

• To develop and validate a novel cardiac risk index, termed RISKO.
• To assess the effectiveness of the RISKO index in predicting the development of symptomatic coronary disease.
• To compare the discriminative power of the RISKO index with the Framingham index.

Main Methods:

• A cohort of 4,066 safety personnel from Los Angeles County was studied.
• Eight established heart disease risk factors were utilized: age, sex, family history, blood pressure, cholesterol, weight, smoking, and exercise.
• A cardiac index (RISKO) was computed for each participant.

Main Results:

• Over the study period, 71 individuals developed coronary disease.
• The computed RISKO index demonstrated significant value in identifying individuals who subsequently developed symptomatic coronary disease.
• The discriminative power of the RISKO index was found to be comparable to that of the Framingham index.

Conclusions:

• The RISKO index, based on eight common risk factors, is a valuable tool for identifying individuals at risk of coronary heart disease.
• The RISKO index offers comparable predictive accuracy to the Framingham index, potentially serving as an effective alternative or adjunct risk assessment tool.
• Further validation in diverse populations is warranted to establish the broad applicability of the RISKO index in cardiovascular risk stratification.
